Description

L'invention a pour objet un dispositif de fabrication d'une lingotière tubulaire de coulée continue. On sait que, dans les installations de coulée continue, l'acier liquide est coulé dans des moules sans fond appelés lingotières dont la paroi est refroidie énergiquement de façon à former une croute solidifiée enfermant l'acier liquide et permettant la production continue d'une barre qui s'échappe par le fond de la lingotière et passe dans un dispositif de refroidissement secondaire où elle achève de se solidifier.The invention relates to a device for manufacturing a tubular ingot mold for continuous casting. It is known that, in continuous casting installations, the liquid steel is poured into bottomless molds called ingot molds whose wall is cooled vigorously so as to form a solidified crust enclosing the liquid steel and allowing the continuous production of a bar which escapes from the bottom of the mold and passes into a secondary cooling device where it completes to solidify.

Pour assurer un refroidissement efficace, la paroi interne de la lingotière est constituée normalement en cuivre.To ensure efficient cooling, the internal wall of the mold is normally made of copper.

Lorsque la lingotière doit avoir une section importante, elle est constituée le plus souvent de quatre plaques formant un rectangle. En revanche, pour les installations de taille moyenne de production de billettes et de blooms, on utilise généralement des lingotières tubulaires constituées d'une enveloppe fermée formant un conduit tubulaire dont la section droite carrée ou rectangulaire, a sensiblement la forme du produit que l'on désire obtenir.When the mold must have a large section, it usually consists of four plates forming a rectangle. On the other hand, for medium-sized installations for the production of billets and blooms, tubular ingot molds are generally used which consist of a closed envelope forming a tubular duct whose square or rectangular cross section has substantially the shape of the product that the we want to get.

Pour tenir compte du retrait qui se produit pendant le refroidissement de l'acier, il est habituel de donner au conduit tubulaire une certaine conicité, les parois latérales étant légèrement inclinées par rapport à l'axe du conduit pour converger vers le centre.To take account of the shrinkage which occurs during the cooling of the steel, it is usual to give the tubular duct a certain taper, the side walls being slightly inclined relative to the axis of the duct to converge towards the center.

En outre, la lingotière est animée d'un mouvement d'oscillation en suivant souvent un trajet en arc de cercle de grand rayon et le conduit tubulaire doit alors étre courbé de telle sorte que son axe forme un arc de cercle de même rayon.In addition, the mold is driven in an oscillating movement, often following a path in an arc of a large radius, and the tubular conduit must then be bent so that its axis forms an arc of a circle with the same radius.

La fabrication des lingotières tubulaires présentent certaines difficultés dues à l'exigence de cette forme courbe et convergente et au fait que l'enveloppe formant le conduit est constituée en cuivre et a donc une épaisseur relativement peu importante.The manufacture of tubular ingot molds presents certain difficulties due to the requirement of this curved and convergent shape and to the fact that the envelope forming the conduit is made of copper and therefore has a relatively small thickness.

1 On a déjà proposé, pour la fabrication d'une lingotière tubulaire en arc de cercle, d'introduire à l'intérieur d'un tube un mandrin de calibrage ayant la forme souhaitée et de tirer le conduit tubulaire contenant le mandrin à travers une filière de façon à obliger les parois du conduit à prendre la forme du mandrin. Une telle méthode ne permet pas de donner aux parois internes du tube la conicité voulue.1 It has already been proposed, for the manufacture of a tubular ingot mold in an arc, to introduce inside a tube a calibration mandrel having the desired shape and to draw the tubular conduit containing the mandrel through a die so as to force the walls of the conduit to take the shape of the mandrel. Such a method does not make it possible to give the internal walls of the tube the desired taper.

On a également proposé de déformer le conduit par explosion pour lui donner la forme d'un moule, mais cette méthode est évidemment asses difficile à mettre en oeuvre.It has also been proposed to deform the pipe by explosion to give it the shape of a mold, but this method is obviously difficult to implement.

L'invention a pour objet un nouveau dispositif permettant d'obtenir facilement des lingotières tubulaires courbes et, si nécessaire, à parois convergentes.The invention relates to a new device for easily obtaining curved tubular ingot molds and, if necessary, converging walls.

Conformément à l'invention, le fond de la glissière de guidage du coin de règlage est constitué par un gabarit de forme cylindrique parallèle à la forme à donner à la face usinée, que le coin de réglage est articulé sur la tige de manoeuvre autour d'un axe parallèle aux génératrices du gabarit cylindrique et que l'une au moins des faces d'appui correspondantes du coin 4 et du porte outil est convexe.According to the invention, the bottom of the guide slide of the adjustment corner is constituted by a template of cylindrical shape parallel to the shape to be given to the machined face, that the adjustment corner is articulated on the operating rod around an axis parallel to the generatrices of the cylindrical template and that at least one of the corresponding bearing faces of the corner 4 and of the tool holder is convex.

L'invention a également pour objet un dispositif de rabotage spécialement adapté pour la fabrication d'une lingotière tubulaire courbe.The invention also relates to a planing device specially adapted for the manufacture of a curved tubular ingot mold.

On sait qu'un dispositif de rabotage comprend, d'une façon générale un outil monté sur un porte-outil animé d'un mouvement longitudinal alternatif par rapport à la pièce à raboter et des moyens permettant de modifier transversalement la position relative de l'outil et de la pièce au début de chaque mouvement alternatif.It is known that a planing device generally comprises a tool mounted on a tool holder driven in a reciprocating longitudinal movement relative to the part to be planed and means making it possible to modify the relative position of the tool and workpiece at the start of each reciprocating movement.

Dans certains dispositifs de rabotage, le moyen de réglage transversal de la position de l'outil par rapport à la pièce est constitué par une pièce formant coin interposé entre le porte-outil et son support auquel elle est fixée par une tige de manoeuvre de longueur réglable ; cette pièce sert d'appui fixe au porte-outil pendant le mouvement alternatif longitudinal et, à cet effet, est guidée dans une glissière fixe parallèle à la direction de déplacement. Le coin s'appuie sur le porte-outil par l'intermédiaire d'une face inclinée coopérant avec une face d'appui correspondante du porte-outil et le réglage de la longueur de la tige de manoeuvre permet de modifier l'enfoncement du coin et par conséquent la position relative transversale de l'outil au début de chaque mouvement alternatif. Dans le dispositif selon l'invention, le fond de la glissière de guidage du coin d'entrainement est constitué par un gabarit de forme cylindrique parallèle à la forme à donner à la face usinée, le coin d'entrainement est articulé sur la tige de manoeuvre autour d'un axe parallèle aux génératrices du gabarit cylindrique et l'une au moins des faces d'appui correspondantes du coin et du porte-outil est convexe.In some planing devices, the means for transversely adjusting the position of the tool relative to the workpiece is constituted by a wedge piece interposed between the tool holder and its support to which it is fixed by a length operating rod. adjustable; this part serves as a fixed support for the tool holder during the longitudinal reciprocating movement and, for this purpose, is guided in a fixed slide parallel to the direction of movement. The wedge rests on the tool holder by means of an inclined face cooperating with a corresponding bearing face of the tool holder and the adjustment of the length of the operating rod makes it possible to modify the depression of the wedge and therefore the relative transverse position of the tool at the start of each reciprocating movement. In the device according to the invention, the bottom of the guide slide of the drive wedge is constituted by a template of cylindrical shape parallel to the shape to be given to the machined face, the drive wedge is articulated on the rod maneuver around an axis parallel to the generatrices of the cylindrical template and at least one of the corresponding bearing faces of the corner and of the tool holder is convex.

Dans un mode de réalisation particulier, l'axe du conduit tubulaire est incliné par rapport à la direction du gabarit d'un angle correspondant à la conicité à donner à la paroi de la lingotière en cours d'usinage.In a particular embodiment, the axis of the tubular conduit is inclined relative to the direction of the template by an angle corresponding to the taper to be given to the wall of the ingot mold during machining.

L'invention sera mieux comprise grâce à la description qui va suivre d'un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés.The invention will be better understood from the following description of a particular embodiment, given by way of example and shown in the accompanying drawings.

La figure 1 est une vue en coupe verticale d'une lingotière tubulaire en cours d'usinage selon l'invention.Figure 1 is a vertical sectional view of a tubular ingot mold during machining according to the invention.

La figure 2 est une vue de dessus, partiellement en coupe selon 11-11 figure 1.Figure 2 is a top view, partially in section according to 11-11 Figure 1.

Sur la figure 1, on a représenté schématiquement une lingotière tubulaire constitué d'une enveloppe fermée en cuivre 1 à l'intérieur de laquelle est ménagé un conduit tubulaire 10 centré sur un axe 100.In FIG. 1, a tubular ingot mold is shown schematically consisting of a closed copper envelope 1 inside which is formed a tubular conduit 10 centered on an axis 100.

Deux des faces latérales opposées 13 et 14 du conduit 10 sont planes alors que les deux autres faces opposées 11 et 12 sont incurvées en forme de portion de cylindre à génératrices perpendiculaires à l'axe 100 qui est lui-même courbé en arc de cercle de rayon égal au rayon d'oscillation de la lingotière.Two of the opposite lateral faces 13 and 14 of the conduit 10 are flat while the other two opposite faces 11 and 12 are curved in the form of a portion of cylinder with generatrix perpendicular to the axis 100 which is itself curved in an arc of a circle. radius equal to the oscillation radius of the mold.

Sur la figure, la lingotière a été représentée en fin d'usinage de façon à faire apparaître les faces cylindriques 11 et 12. Cependant, avant l'usinage, la lingotière brute de fonderie est limitée par des parois internes 15, qui dans l'exemple représenté sont supposées planes et indiquées en trait mixte sur la figure.In the figure, the ingot mold has been shown at the end of machining so as to reveal the cylindrical faces 11 and 12. However, before machining, the raw foundry mold is limited by internal walls 15, which in the example shown are assumed to be flat and indicated in phantom in the figure.

Pour son usinage, la lingotière brute est placée sur un plateau 2, fixé en position règlable sur un bâti 40 et sur lequel est ménagé un orifice 21 correspondant au conduit 10 et de section suffisante pour permettre le dégagement du dispositif de rabotage qui est placé à l'intérieur du conduit tubulaire 10 et comprend un porte outil 3, un coin d'appui 4 et une glissière de guidage 5.For its machining, the raw ingot mold is placed on a plate 2, fixed in adjustable position on a frame 40 and on which is formed an orifice 21 corresponding to the conduit 10 and of sufficient section to allow the release of the planing device which is placed at inside the tubular conduit 10 and comprises a tool holder 3, a support corner 4 and a guide slide 5.

L'outil de rabotage 31 est fixé de façon classique sur le porte-outil 3 qui sur sa face opposée à l'outil et tournée vers la glissière 5, est muni d'une face d'appui 32 inclinée par rapport à la direction de déplacement de l'outil et sur laquelle s'appuie le coin 4. Celui-ci est muni du côté du porte outil 3, d'une face d'appui inclinée 41 coopérant avec la face d'appui 32 du porte outil 3. Du côté opposé au porte outil, le coin 4 est muni d'une face de guidage constituée de deux patins 42 qui s'appuient sur le fond de la glissière 5, celle-ci ayant une section en U et comportant deux ailes latérales 51 de maintien du coin 4.The planing tool 31 is conventionally fixed to the tool holder 3 which on its face opposite the tool and facing the slide 5, is provided with a bearing face 32 inclined with respect to the direction of displacement of the tool and on which the wedge 4 rests. The latter is provided on the side of the tool holder 3 with an inclined bearing face 41 cooperating with the bearing face 32 of the tool holder 3. From side opposite to the tool holder, the corner 4 is provided with a guide face consisting of two pads 42 which bear on the bottom of the slide 5, the latter having a U-shaped section and comprising two lateral wings 51 for holding from corner 4.

Selon une caractéristique essentielle de l'invention, le fond de la glissière 5 est constitué par un gabarit 6 dont la forme correspond à celle que l'on désire donner à la face usinée. D'une façon générale, le gabarit 6 aura donc la forme d'une surface cylindrique convexe pour l'usinage de la face concave 11 et, inversement, concave pour l'usinage de la face convexe 12.According to an essential characteristic of the invention, the bottom of the slide 5 is constituted by a template 6 whose shape corresponds to that which it is desired to give to the machined face. Generally, the template 6 will therefore have the shape of a convex cylindrical surface for the machining of the concave face 11 and, conversely, concave for the machining of the convex face 12.

Le porte-outil 3 avec l'outil 31 et le coin d'appui 4 sont animés d'un mouvement longitudinal alternatif par rapport à la lingotière 1 et à la glissière de guidage 5.The tool holder 3 with the tool 31 and the support corner 4 are driven in a reciprocating longitudinal movement relative to the ingot mold 1 and to the guide slide 5.

A cet effet, le plateau 2 de support de la lingotière 1 et la glissière 5 avec le gabarit 6 sont solidaires du bâti 40 de la machine sur lequel est guidé un coulisseau 8 animé d'un mouvement axial alternatif par des moyens non représentés et auquel sont reliés le porte outil 3 et le coin 4 par l'intermédiaire d'une tige de manoeuvre 7.To this end, the plate 2 for supporting the ingot mold 1 and the slide 5 with the template 6 are integral with the frame 40 of the machine on which is guided a slide 8 driven by an alternating axial movement by means not shown and to which the tool holder 3 and the corner 4 are connected by means of an operating rod 7.

Le plateau de support 2 de la lingotièrel est fixé sur le bâti 40 pendant une passe d'usinage, mais sa position peut être réglée de façon à modifier la zone d'action de l'outil 31. D'une façon générale, le. plateau peut être monté sur le bâti 40 à la manière d'une table de fraiseuse.The support plate 2 of the ingot mold is fixed on the frame 40 during a machining pass, but its position can be adjusted so as to modify the zone of action of the tool 31. In general, the. tray can be mounted on the frame 40 in the manner of a milling table.

L'effort de coupe ainsi que des moyens élastiques schématisés sur la figure par un ressort 34 déterminent un appui permanent du porte-outil 3 contre le coin 4 et de celui-ci contre le fond de la glissière 5 constitué par le gabarit cylindrique 6. La queue du porte outil 3 est articulée sur le coulisseau 8 autour d'un axe 33 et le coin 4 est également monté articulé autour d'un axe 70 à l'extrémité de la tige de manoeuvre 7 reliée au coulisseau 8 et dont la longueur peut être modifiée au moyen d'un organe de réglage 71.-Les axes d'articulation 33 du porte outil 3 et 70 du coin 4 sont parallèles aux génératrices du gabarit cylindrique 6.The cutting force as well as elastic means shown diagrammatically in the figure by a spring 34 determine a permanent support of the tool holder 3 against the wedge 4 and of this against the bottom of the slide 5 formed by the cylindrical template 6. The tail of the tool holder 3 is articulated on the slide 8 around an axis 33 and the corner 4 is also mounted articulated around an axis 70 at the end of the operating rod 7 connected to the slide 8 and whose length can be modified by means of an adjustment member 71.-The articulation axes 33 of the tool holder 3 and 70 of the corner 4 are parallel to the generatrices of the cylindrical template 6.

De la sorte, le coin 4 peut rester appliqué contre le gabarit 6 au cours de son déplacement le long de celui-ci. D'autre part, la face d'appui inclinée 41 du coin 4 a une forme cylindrique à génératrices parallèles à celles du gabarit 6, dont la courbure est déterminée de façon que la réaction de l'outil 31 passe constamment à l'intérieur de la surface de guidage 42 et que la profondeur de coupe reste constante. Ainsi, lorsque le porte outil 3 se déplace par rapport à la lingotière, le coin 4, en glissant le long du gabarit 6 détermine l'usinage d'une surface pratiquement superposable à celle du gabarit 6.In this way, the wedge 4 can remain applied against the template 6 during its movement along the latter. On the other hand, the inclined bearing face 41 of the corner 4 has a cylindrical shape with generatrix parallel to those of the template 6, the curvature of which is determined so that the reaction of the tool 31 passes constantly inside the guide surface 42 and that the depth of cut remains constant. Thus, when the tool holder 3 moves relative to the ingot mold, the corner 4, by sliding along the template 6 determines the machining of a surface practically superimposable on that of the template 6.

Par ailleurs, le réglage de la longueur et la tige de manoeuvre 7 du coin 4 au moyen du dispositif 70 permet en fin de course, de déplacer axialement le coin 4 par rapport au porte outil. En règlant la position du coin 4 le long de la face d'appui inclinée 32, on peut donc donner un mouvement d'avance à l'outil 31 et régler la profondeur de la passe.Furthermore, the adjustment of the length and the operating rod 7 of the corner 4 by means of the device 70 allows, at the end of the stroke, to move the corner 4 axially relative to the tool holder. By adjusting the position of the corner 4 along the inclined bearing face 32, it is therefore possible to give the tool 31 a forward movement and adjust the depth of the pass.

En position basse, un déplacement relatif vers le haut du coin 4 par rapport au porte outil 3 éloigne l'outil 31 de la face à usiner et permet donc de le remonter facilement.In the low position, a relative upward movement of the corner 4 relative to the tool holder 3 moves the tool 31 away from the face to be machined and therefore makes it possible to reassemble it easily.

En outre, le dispositif permet également de réaliser facilement des faces convergentes ayant la conicité désirée. Pour cela, il suffit en effet, d'incliner la lingotière par rapport au plateau, par exemple au moyen de cales, d'un angle égal à l'angle de conicité recherché ou bien inversement, d'incliner légèrement le gabarit par rapport au fond 52 de la glissière 5.In addition, the device also makes it possible to easily produce converging faces having the desired taper. To do this, it suffices in fact to tilt the mold relative to the plate, for example by means of shims, at an angle equal to the desired taper angle, or vice versa, to slightly tilt the template relative to the bottom 52 of slide 5.

Bien entendu, l'invention ne se limite pas au mode de réalisation représenté, d'autres variantes pouvant être imaginées en employant des moyens équivalents.Of course, the invention is not limited to the embodiment shown, other variants that can be imagined by using equivalent means.
